To use concord to convert a few coordinates from the keyboard use the command
C:> concord
This will prompt for the input and output coordinate systems and prompt for input and output file names as shown in the example below. This illustrates converting New Zealand Map Grid coordinates to New Zealand Transverse Mercator. No input and output file names are specified, so the the coordinates are entered from the keyboard and displayed on the screen.
This same conversion could have been putting the coordinates into an input file (say input.txt) and running the command:
C:> concord -inzmg,en -onztm,en -n10 input.txt output.txt
C:\>concord
concord: Coordinate conversion program
Input coordinates:
Enter input circuit code or ?: nzmg
Coordinate order can be EN, ENH, ENO, NE, NEH, or NEO (O = ortho. height)
Enter input coordinate order(default EN): en
Output coordinates:
Enter output circuit code or ?: nztm
Coordinate order can be EN, ENH, ENO, NE, NEH, or NEO (O = ortho. height)
Enter output coordinate order(default EN): en
Enter number of decimal places for output (default 3): 3
Each point you convert can have a name. If you want to use names you must
specify the length of the longest name you want to use
Enter maximum name length, or 0 for no names (default 0): 10
You can enter the coordinates to convert yourself, or read them from a file
If you want to read them from a file then specify the name of the file,
otherwise just press Enter
Enter coordinate input filename:
If you want the output to go to a file, enter the file name
Enter output file name:

concord - coordinate conversion program
Input coordinates: New Zealand Map Grid
Output coordinates: New Zealand Transverse Mercator Projection
You can now enter coordinates you want converted. Your input should look
something like this:
STN_3 315378.28 728910.43
Each item should be separated by at least one blank space.
The name cannot include blanks.
When you have finished enter a blank line to quit the program
Enter name, easting, northing: point1 2429637.34 5931152.65
1519673.605 5369483.399
Enter name, easting, northing: point1 2512939.36 6061427.7
1602951.181 5499699.403
Enter name, easting, northing:
